원적외선 방사 수지 조성물Far Infrared Radiation Resin Composition
[발명의 상세한 설명]Detailed description of the invention
본 발명은 원적외선 방사 폴리프로필렌 수지 조성물에 관한 것으로서, 구체적으로는 굴곡탄성율과 표면광택이 우수하고, 야채의 선도 보존효과가 뛰어나서 용기(容器) 제조에 적합한 원적외선 방사(far infrared radiation) 수지 조성물에 관한 것이다.The present invention relates to a far-infrared radiation polypropylene resin composition, and more particularly, to a far-infrared radiation resin composition suitable for producing a container having excellent flexural modulus and surface gloss and excellent freshness preservation effect of vegetables. will be.
빛의 파장 중 원적외선은 5.6∼1,000 마이크론 영역에 해당되며, 이중 4.6∼18 마이크론 영역의 원적외선은 생체의 분자나 원자와 공명, 진동 등을 일으키는 특성이 있어 세포조직의 활성화, 효소생성의 촉진, 자기발열과 같은 효과를 나타내는 것으로 알려져 있다. 이러한 효과를 나타내는 물질로서 맥반석, 규조토와 같은 많은 원적외선 방사 세라믹스가 알려져 있다.Among the wavelengths of light, far infrared rays correspond to 5.6 to 1,000 microns, and among them, far infrared rays of 4.6 to 18 microns have characteristics that cause resonance and vibration with molecules and atoms of living organisms. It is known to exhibit the same effect as fever. As materials exhibiting such effects, many far-infrared radiation ceramics such as elvan and diatomaceous earth are known.
원적외선 방사 세라믹스는 원적외선을 다량 방사하는 물질로서 상기와 같은 효과의 이용을 목적으로 히터, 후라이팬, 돌구이판, 식기, 침구류, 마사지기, 전자렌지, 냉장고, 플라스틱용기 등 각종 건강 용품, 주방용품, 전기제품 등 생산에 널리 적용되고 있다. 이중 일반 가정에서 흔히 사용하고 있는 원적외선 방사 제품은 야채 보존용 플라스틱 용기이며, 이러한 용기는 표면광택, 굴곡탄성율, 원적외선 방사율 및 야채 선도 보존효과가 우수할수록 상품으로서의 가치가 우수한 것이 된다.Far-infrared radiation ceramics is a material that emits a large amount of far-infrared rays, for the purpose of using the above effects, various health products such as heaters, frying pans, stone plates, tableware, bedding, massage machines, microwave ovens, refrigerators, plastic containers, kitchen appliances, It is widely applied to the production of electrical appliances. Far-infrared radiation products commonly used in households are plastic containers for vegetable preservation, and the more excellent the surface gloss, flexural modulus, far-infrared emissivity and vegetable freshness preservation effect, the better the product value.
종래의 원적외선 방사 수지 용기의 경우 냉장고와 같은 저온에서 사용시 취약점인 용기의 충격강도 향상을 위해 메트릭스 수지로서 에틸린의 함유량이 높은 폴리프로필렌 블록 코폴리머를 사용하기도 하였는데, 이 경우 용기의 저온 충격강도는 양호하였으나 용기의 얇은 두께로 인하여 굴곡강도가 낮아 취급이 불편하고 에틸렌의 함량이 높은 수지는 표면광택이 떨어지게 되므로 외관 불량으로 용기의 상품가치가 떨어지는 단점이 있었다.In the case of the conventional far-infrared radiation resin container, a polypropylene block copolymer having a high content of ethylene is used as a matrix resin to improve the impact strength of the container, which is a weak point when used at a low temperature such as a refrigerator. In this case, the low temperature impact strength of the container is It was good, but due to the thin thickness of the container, the flexural strength was low, which made it inconvenient to handle, and the resin having high ethylene content had a poor surface gloss.
종래 용기 제조용 원적외선 방사 수지 조성물은 주로 입도 분포가 4∼10 마이크론 범위의 원적외선 방사 세라믹스를 혼합하여 사용하였다. 이 경우 야채 선도 보존 기능을 높이기 위해서는 세라믹스의 사용량을 높여야 하는데 세라믹스의 함량이 높아지게 되면 수지와의 분산성이 떨어져서 제조 공정중 혼련 불량, 기기의 마모 특히 압축기의 스크류, 실린더 등의 마모 및 이로 인한 생산성의 저하, 가공비의 상승 등이 따르게 되며 제조된 용기의 물성과 표면 광택도가 떨어진다는 문제가 있었다.In the prior art, the far-infrared radiation resin composition for container manufacture was mainly used by mixing far-infrared radiation ceramics having a particle size distribution in the range of 4 to 10 microns. In this case, the amount of ceramics should be increased in order to increase the freshness of the vegetable freshness. If the content of the ceramics increases, the dispersibility with resin decreases, and there is a poor kneading during the manufacturing process, the wear of the device, especially the screw of the compressor, the cylinder, etc. This is accompanied by a decrease in the processing cost and the increase in the processing cost, there was a problem that the physical properties and surface gloss of the manufactured container is poor.
종래의 야채 선도 보존을 위한 원적외선 방사 수지 조성물의 경우 단지 원적외선의 방사가 비교적 많은 규소산화물 또는 백색도가 뛰어난 티탄산화물 등을 분말화하여 용기 제조시에 혼합시켜 제조하였던 것으로서, 이들 용기에서 방사되는 원적외선은 세라믹 분말 자체에서 방사되는 값을 측정하여 제시한 것 뿐이어서 실제 플라스틱 용기에 소량 적용시 그 값이 그대로 발현되는 것도 아니어서 세라믹스 자체의 높은 원적외선 방사율과는 달리 야채의 선도 보존효능은 일반 플라스틱용기와 비교하여 특별하게 우수한 특성을 나타내는 못하였다. 또한 원적외선의 방사율을 높이기 위해 선도 보존 효과를 고려치 않고 무리하게 세라믹스를 혼입함으로써 세라믹 다량 혼입에 따른 혼련, 기기 마모, 제품의 표면 불양 등 상기한 문제점의 유발 가능성이 더욱 높았다.In the case of the conventional far-infrared radiation resin composition for preserving the freshness of the vegetable, only the far-infrared radiation of silicon oxide or titanium oxide with excellent whiteness is powdered and mixed at the time of manufacturing the container, and the far-infrared radiation emitted from these containers It is only a measure of the value emitted from the ceramic powder itself, and the value is not expressed as it is applied to the actual plastic container. Therefore, unlike the high far-infrared emissivity of the ceramic itself, the freshness of the vegetable is the In comparison, it did not show particularly excellent characteristics. In addition, in order to increase the emissivity of far-infrared rays, by incorporating the ceramics without considering the freshness preservation effect, the above-mentioned problems such as kneading due to the incorporation of a large amount of ceramics, abrasion of the product, and poor surface of the product were more likely to be caused.
상기한 문제점을 고려하여본 발명의 원적외선 방사 수지 조성물은 다음과 같은 조성으로 구성하였다.In view of the above problems, the far-infrared radiation resin composition of the present invention was composed of the following composition.
메트릭스 수지는 가공성 및 굴곡강도, 광택이 우수한 호모 폴리프로필렌 수지를 사용하였으며, 비닐리덴 플루오라이드(vinylidene fluoride)와 헥사플루오로프로필렌(hexa-fluoropropylene)의 공중합체 90중량부와 마이크로탤크(microtalc) 10중량부로 이루어진 불화탄소계 에라스토머(이하 "불화탄소계 에라스토머"라고 한다)를 소량 첨가하여 가공성의 향상은 물론 표면광택 및 외관의 미려함을 유지할 수 있었다. 또한 원적외선 방사 세라믹스 분말은 원적외선 방사량이 큰 실리카, 물의 자정 효과가 우수한 것으로 알려져 있는 알루미늄, 용기의 외관 및 방사율 보강을 위한 티타늄 등의 산화물을 주성분으로 하며, 이러한 성분외에 지르코늄, 마그네슘, 철 등 무기 금속 산화물을 처방하여 각 파장별 원적외선 방사를 보강 증가시켰다.As the matrix resin, homopolypropylene resin having excellent processability, flexural strength, and gloss was used, and 90 parts by weight of a copolymer of vinylidene fluoride and hexafluoropropylene and a microtalc 10 were used. A small amount of carbon fluoride-based elastomer (hereinafter referred to as "fluorocarbon-based elastomer") composed of parts by weight was able to improve workability as well as maintain surface gloss and beauty of appearance. In addition, the far-infrared radiation ceramics powder is mainly composed of silica, which is known to have high far-infrared radiation, and aluminum, which is known to have excellent self-cleaning effect of water, and titanium, such as titanium for reinforcing the appearance and emissivity of containers, and inorganic metals such as zirconium, magnesium and iron. Oxides were prescribed to enhance far-infrared radiation at each wavelength.
호모폴리프로필렌은 원적외선 방사 세라믹스를 비롯한 기타 첨가제와의 양호한 혼련 및 가공을 위하여 파우더 형태의 용융지수 8∼15g/10min의 것이 좋으며, 함량은 세라믹스와의 혼련성, 원적외선 방사율, 제품 물성 및 가격 등을 고려할 시 93∼97 중량부가 적당하다. 또한 원적외선 방사 세라믹스는 입도가 0.5∼2.0 마이크론의 것으로서 3∼7 중량부가 좋으며, 3 중량부 이하에서는 굴곡탄성율 및 원적외선의 방사율이 낮고 야채 선도 보존효과가 저하되며, 7중량부 이상에서는 세라믹스의 양은 많아지나 더 이상의 원적외선 방사율 및 선도 보존효과의 증가없이 메트릭스 수지와의 혼련 불량 및 요구 물성 저하의 문제가 발생할 수 있다. 그리고 불화탄소계 에라스토머는 분자량이 20,000∼25,000 범위의 것으로서 함량은 전체 조성물에 대하여 0.08∼0.1 중량부로 하는 것이 적당하며, 0.08 중량부 이하에서는 효과 발현이 부족하고 0.1 중량부 이상에서는 효과의 증대의 변화가 거의 없다.Homopolypropylene has good melt index of 8 ~ 15g / 10min in powder form for good kneading and processing with far-infrared radiation ceramics and other additives.The content is homogeneous with ceramics, far-infrared emissivity, product properties and price. In consideration of 93 to 97 parts by weight is appropriate. In addition, the far-infrared radiation ceramics have a particle size of 0.5 to 2.0 microns, and 3 to 7 parts by weight is good. At 3 parts by weight or less, the flexural modulus and the emissivity of far infrared rays are low, and the vegetable freshness preservation effect is lowered. However, problems of poor kneading with the matrix resin and deterioration of the required physical properties may occur without further increasing the far-infrared emissivity and freshness preservation effect. In addition, the fluorocarbon elastomer has a molecular weight in the range of 20,000 to 25,000, and the content thereof is appropriately set to 0.08 to 0.1 parts by weight based on the total composition. There is little change.
한편 원적외선 방사 세라믹스의 조성에 있어서 산화알루미늄(Al2O3)의 함량은 60∼70 중량부가 적당한데, 60 중량부 이하에서는 선도 유지 효과가 다소 떨어지며 70 중량부 이상 처방할 경우 원적외선 방사율을 감소시킬 우려가 있다. 또한 이산화티탄(TiO2)의 함량은 20∼25 중량부가 좋으며, 이는 원적외선 방사율의 보강 및 용기 제조시 망간, 철 등의 무기 금속 산화물에 의해 용기의 외관 색깔이 연회색으로 변하는 것을 방지하기 위해서이다. 여기에 이산화규소(SiO2)를 5∼10 중량부 처방하여 원적외선 방사율을 증가시켜 선도 보존효과를 더욱 보강시킨다. 이렇게 하여 구성된 세라믹스에 5 중량부 이내의 산화지르코늄(ZrO2), 산화칼슘(CaO), 산화제이철(Fe2O3), 산화나트륨(Na2O), 산화칼륨(K2O) 등 무기 금속 산화물을 처방하여 파장별 원적외선의 방사를 보상함으로써 4.6∼18 마이크론내 전 영역에 있어서 고르게 원적외선이 방사되는 세라믹스가 되게 한 것이 좋다.Meanwhile, the content of aluminum oxide (Al 2 O 3 ) in the composition of far-infrared radiation ceramics is 60 to 70 parts by weight, but less than 60 parts by weight, the freshness retention effect is somewhat lower, and when more than 70 parts by weight, far-infrared emissivity may be reduced. There is concern. In addition, the content of titanium dioxide (TiO 2 ) is 20 to 25 parts by weight is good, in order to prevent the appearance color of the container light gray by the inorganic metal oxides such as manganese, iron, etc. during the reinforcement of far-infrared emissivity and container manufacturing. Silicon dioxide (SiO 2 ) is prescribed in 5 to 10 parts by weight to increase the far-infrared emissivity to further reinforce the freshness preservation effect. Inorganic metals such as zirconium oxide (ZrO 2 ), calcium oxide (CaO), ferric oxide (Fe 2 O 3 ), sodium oxide (Na 2 O), potassium oxide (K 2 O), etc., within 5 parts by weight of the ceramics thus constructed. It is desirable to prescribe oxides to compensate the radiation of far-infrared rays for each wavelength, so that the far-infrared rays are evenly distributed in all regions within 4.6 to 18 microns.
성형된 용기의 굴곡탄성율과 표면광택이 우수하고, 야채의 선도 보존 효과가 뛰어난 본 발명의 원적외선 방사 수지 조성물의 제조방법에 대하여 이하 실시예를 들어 구체적으로 설명한다.The method for producing the far-infrared radiation resin composition of the present invention excellent in the flexural modulus and surface gloss of the molded container and excellent in the freshness preservation effect of vegetables will be described below with reference to Examples.
